The company
A Honey Grove septic company with its brand on the door.
Diamond E Environmental Services is based in Honey Grove, in eastern Fannin County. The company started in 2025 with a clear focus, lettered right on the tank: septic pumping and luxury restroom trailers.
The work runs across Northeast Texas and into southern Oklahoma: pumping tanks for homes, farms, shops and RV parks; keeping aerobic systems on the inspection schedule Texas requires; and setting out restroom trailers and portable toilets for weddings, reunions, job sites and events.
The Diamond E mark, a cut diamond joined to an E, rides on the truck door the way a ranch brand rides on a gate. It’s the company’s promise that the work is done right and the yard is left the way it was found.
What we stand on
How we work.
Around the clock
Their listing says it plainly: 24 hours a day. Septic trouble rarely waits for business hours.
One call, two jobs
The same crew that pumps your tank can bring the restroom trailer for the wedding on the back forty.
Clay-country know-how
Blackland soil is hard on septic systems, and it’s the ground we work in, from Honey Grove to the Red River.
Straight answers
We tell you what we found in the tank and what it means. No scare talk, no upsell.
